When implementing cooling solutions for electronic equipment, system designers are confronted with a complex set of variables. The cooling requirements are typically dynamic, and ambient temperatures ...

PWM or Pulse Width Modulation has generally been regarded as too complicated for PC fan speed control compared against using rheostats or linear voltage regulators such as the LM317. I present here a ...

A few weeks ago, I saw a reader’s question about how to run PS3 cooling fans using an external electronics circuit. At the time I was busy with some other projects. The other day, I decided to put my ...

Here is a simple mod to allow the speed of any 12V fan to be varied. All we need to do is insert a rheostat or variable resistor in the 12V wire to the fan. The rheostat should be rated at least 3 ...

The way we control the speed of fan motors or pump motors has tremendously changed in the past two decades with the introduction of variable-frequency drives (VFDs), aka variable-frequency controllers ...

The simplest of fan-control schemes an on-off switch is simple but inefficient, because it provides more cooling than necessary most of the time. When The simplest of fan-control schemes — an on-off ...

High-frequency dc fans feature pulse-width-modulation (PWM) fan-speed control that eliminates motor commutation noise. The PWM ramps up linearly from a 20% duty cycle up to the fan's maximum rated ...

Windows PCs and laptops require a dedicated fan to support heat dissipation. The fan helps keep the hardware cool and ensures it doesn’t overheat in any intensive work or task. During peak performance ...

The Leviton Decora Smart Wi-Fi 4-Speed Fan Controller is a very, good product; it just isn’t the best in its class. I used to recommend picking one smart home ecosystem and sticking with it. Start ...

I’ve long considered Lutron Caseta the most elegant and user-friendly HomeKit lighting solution. Lutron makes the wall switch smart and works with standard dimmable bulbs; other solutions put the ...

Typically, CPU fan noises are heard when you reboot your PC (the whirring sound you may have heard upon startup) and it goes on to decline as the startup process completes. The purpose of fans on your ...
